Refraction in Media with a Negative Refractive Index
... refraction materials (NIM). The quantities, S, u, p, refer to the composite system consisting of EM field and material. As a result of k and S being antiparallel, the refraction of an EM wave at the interface between a positive n and a negative n material would be at the ‘‘wrong’’ side relative to t ...

... b) Φ = BA cos θ = (1.22x 10−5T )(0.004m)2 cos 0 = 2.0x 10−10Wb c) Since the current is decreasing, Bw is decreasing, so the magnetic flux in the loop is decreasing. To oppose the change a current is induced in coil 2 that produces a B-field in the same direction as the Bw-field inside the loop d) Il ...

... Charge is conserved, meaning it cannot be created or destroyed, only transferred from one location to another. In all atoms, electrons (qe) have negative charge and protons (qp) have positive charge. Charge is quantized, meaning it comes in discrete amounts (like money). total charge = integer x fun ...
